oh lawd, I seen this in my textbook this year but I haven't learnt it yet, sorry :/
oh okay well thanks for looking at it :/
what is the question ? like what we have to do with that ?
I have no clue on how to do the question. It just say evaluate then the image i posted.
|dw:1439566610288:dw|
|dw:1439566827777:dw| there are total 7 term start from 1 a number which is raising to the power is ration
so replace n by 2 to find 2nd term 3 to find 3rd term untill 7
|dw:1439566934306:dw|
we just need that circle part n= terms that you have to find starting from 1 to 7 here i plugin 2 to find 2nd term \[\huge\rm 2(-2)^{\color{red}{2}-1}\] like this now solve
would it be -4?
yes right !
so i just keep plugging number in till i get to 7? Or could i just skip to 7?
wait a sec let me solve it first been a year haven't done question like this :/
you have to find all terms then add them.
we have to evaluate if it say find sum then we can use the formula.
Nnesha its not function like power series right ?
wait doesn't matter you will get the same answer no need to find all terms
its just total numbers i think
\[\huge\rm S_n = \frac{ a_1(1-r^n )}{ 1-r }\] use this formula plug in the r and n values then sovle
a_1= first term r= ratio n= number of total terms!
yeah sum of all 7 terms but we can use that formula to find sum of 7 terms that way we don't have to find 3,4,5,6,7 terms
so i could do it either way and get the same answer?
yes right
okay thank you!!
my pleasure!
